肺内孤立性微小结节的影像与病理学对照分析

目的 探讨肺内孤立性微小结节的病理学诊断与手术前影像学特征性分析的对比以及对临床的指导意义.方法 37例经普通X射线平片、CT影像检查发现的肺内孤立性微小结节病变,通过手术获得病理学诊断,对照手术前肺内孤立性微小结节影像诊断、鉴别诊断结果,进行回顾性分析,以提高影像诊断与病理学诊断的符合率.结果 18例患者术前诊断为肺癌,其中11例CT影像具有恶性征象;19例术前诊断为肺部良性病变.经电视胸腔镜手术肺部微小结节的诊断和治疗,均获得明确的病理学诊断.其中恶性病变9例(24.3%),良性病变28例(75.7%);仅6例(54.5%)术前具有"恶性"影像学特征的患者最终确诊为恶性病变.结论 医学影像学特征性分析有局限性;对于临床发现的肺部孤立性微小结节,电视胸腔镜手术具有明显的微创优势,可作为及时准确获取病理学诊断的首选方法.

Imaging characteristics and pathologic diagnosis of lung isolated tiny nodular lesions

Objective To discuss the significance of comparison between pre-operational imaging characteristics and pathology diagnosis. Methods Thirty-seven cases involved in isolated tiny nodular lesions detected by X-ray and CT. All cases were confirmed by pathologic examination. Results Eighteen cases were diagnosed as lung cancer and 19 cases were diagnosed as benign lesions before operation. Final diagnosis was conducted on all of the cases. Of them, there were 9 malignant and 28 benign cases. Only 6 cases of lung cancer were consistent with the pre-operational diagnosis. Conclusion Imaging characteristics are limited and video-assisted thoracoscopic surgery can be the first choice in the confirmation diagnosis of isolated tiny nodular lesions.
